I didn't stop and photograph while I was painting today. Here, this painting is almost done. I will change the top background color probably to flat blue, darken the highlight on the left side of the dog's back, add some indication of lettering on the tag and soften or break up the strong dark line under his chest (thanks, Lydia, Maria and Kat!)
Once those corrections are done, I'll reevaluate.
Artist Note: I especially liked the olive green in the blacks of this particular dog instead of the blues that I usually use to highlight the blacks.
